Shares of CoStar Group cratered as much as 14% from their prior close after the real-estate data giant delivered a paradox: record revenue, surging profits, raised guidance — and a bookings number that sent a chill through the investor base. Q3 revenue hit a record $952 million, up 14% year-over-year , and adjusted net income rose 59% to $153 million, with adjusted EPS of $0.38, up 65% . That beat the consensus estimate of $0.33 by over 15% . Yet the stock closed the regular session down 5% at $32.01 and sank further to $29.00 after hours.

  • Bookings Collapsed — and That's a Leading Indicator of Future Revenue. Net new bookings — a measure of freshly signed contracts minus cancellations — came in at just $37 million , nearly halved from the $69 million reported in Q2 . In Q1, bookings were $67 million . This sharp sequential decline suggests the sales engine is stalling, not accelerating. Bookings feed tomorrow's subscription revenue, so even with today's headline beat, the pipeline to sustain 14% growth looks considerably thinner.

  • Raised Guidance Couldn't Paper Over the Cracks. CoStar lifted its full-year 2026 revenue outlook to $3.75–$3.77 billion and adjusted EBITDA guidance to $820–$840 million . CEO Andy Florance emphasized that EBITDA "doubled year-over-year" and "was considerably above the high end" of prior guidance . But investors have learned to look past margin improvement driven by cost-cutting — the company flagged roughly $150 million in annualized cost savings — when the organic demand signal is weakening. Profits from spending less aren't the same as profits from selling more.

  • A $730 Million Acquisition Adds Uncertainty at a Fragile Moment. CoStar simultaneously announced a deal to buy Vexcel, a provider of high-resolution aerial imagery covering 45 countries, for $730 million in cash . The deal is expected to boost adjusted earnings in its first full year , but deploying three-quarters of a billion dollars while bookings are decelerating raises questions about capital priorities. Vexcel generates over $140 million in trailing twelve-month revenue, growing above 30% , offering legitimate data assets — but integration risk comes atop a sales force already undergoing restructuring at its residential marketplace .

  • The Stock's Brutal Year Reflects a Deeper Trust Deficit. Shares are down more than 50% from their 52-week high of roughly $79, and the selloff signals that Wall Street demands proof of durable demand growth, not just margin engineering. Until bookings re-accelerate, each beat-and-raise quarter may be met with skepticism rather than applause.
